Benchmarking in healthcare, particularly in the context of complex surgical procedures like pancreatic surgery, plays a pivotal role in comparing and evaluating the quality of care provided to patients. There is a growing body of evidence validating existent metrics and introducing new ones in the pursuit of safety and excellence in pancreatic surgery. A systematic review adhering to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted on metric development and validation across multiple databases, including PUBMED Medline, Scopus, and Web of Science, until February 2024. The extracted data were categorized into three domains according to the Donabedian model: structure, process, and outcomes. Thirty-four studies were deemed eligible for inclusion in this review. Among these articles, 20 contributed to metric development, while 14 studies validated them. A total of 234 metrics were identified across the 34 studies, of which 185 were included in the analysis. Thirty-three of these metrics were relative to structure, 79 to processes, and 73 to outcomes. The distribution of metric domains across the included studies revealed that structure, process, and outcome domains were reported in 12, 26, and 26 studies, respectively. In conclusion, this systematic review underscores the heterogeneity in metric development methodologies and the varying degrees of consensus among different quality indicators, despite the growing interest in benchmarking in pancreatic surgery. This review aims to inform future research efforts and contribute to the ongoing pursuit of excellence in pancreatic surgical care. [ABSTRACT FROM AUTHOR]

Arterial variations in the liver's blood supply play a pivotal role in the success of pancreatoduodenectomy (PD), impacting both its technical execution and oncological outcomes. Among these variations, a common hepatic artery arising from the superior mesenteric artery (SMA) occurs in about 3% of cases. An exceptionally rare variation is the intrapancreatic common hepatic artery (IPCHA). Preserving or reconstructing the IPCHA is vital during PD to prevent liver and biliary necrosis. Particularly for cases of pancreatic cancer with high rates of intrapancreatic perineural spread, preserving IPCHA without compromising radicality presents challenges. We present a detailed report of the technique used for PD in the presence of IPCHA. Surgical technique details include a pylorus-preserving PD with the Cattell–Braasch maneuver, an artery-first approach, and meticulous dissection using "cold" scissors. We emphasize the importance of strategic surgical planning based on high-quality imaging studies, underscoring the need for pancreatic surgeons to be proficient in managing variations in visceral vessels. In conclusion, this case underscores the significance of navigating rare arterial variations in liver supply during PD, highlighting the necessity for meticulous surgical planning and execution.

Sporadic intra-abdominal desmoid tumors are rare and known to potentially occur after trauma including previous surgery, although knowledge of the underlying pathogenetic mechanism is still limited. We reviewed the recent literature on sporadic intraabdominal desmoids and inflammation as we investigated the mutational and epigenetic makeup of a case of multiple synchronous mesenterial desmoids occurring after necrotizing pancreatitis. A 62-year-old man had four mesenteric masses up to 4.8 cm diameter detected on CT eighteen months after laparotomy for peripancreatic collections from necrotizing pancreatitis. All tumors were excised and diagnosed as mesenteric desmoids. DNA from peripheral blood was tested for a multigene panel. The tumour DNA was screened for three most frequent β-catenin gene mutations T41A, S45F and S45P. Expression levels of miR-21-3p and miR-197-3-p were compared between the desmoid tumors and other wild-type sporadic desmoids. The T41A CTNNB1 mutation was present in all four desmoid tumors. miR-21-3p and miR-197-3p were respectively upregulated and down-regulated in the mutated sporadic mesenteric desmoids, with respect to wild-type lesions. The patient is free from recurrence 34 months post-surgery. The literature review did not show similar studies. To our knowledge, this is the first study to interrogate genetic and epigenetic signature of multiple intraabdominal desmoids to investigate potential association with abdominal inflammation following surgery for necrotizing pancreatitis. We found mutational and epigenetic features that hint at potential activation of inflammation pathways within the desmoid tumor. [ABSTRACT FROM AUTHOR]

Aim of this study is to compare early post-operative outcomes and patient's satisfaction after skin-sparing and/or nipple-sparing mastectomy (SSM/SNSM) followed either by breast reconstruction with one-stage prepectoral implantation or two-stage technique for breast cancer (BC) or BRCA1/2 mutation. From January 2018 to December 2021, 96 patients (mean age of 51.12 ± 10.9) underwent SSM/SNSM and were divided into two groups: in group A (65 patients, 67.7%), mastectomy was followed by one-stage reconstruction; in group B (31 patients, 32.3%) by two-stage. Operative time was significantly longer in A vs. B (307.6 ± 95.7 vs. 254.4 ± 90.91; P < 0.05). Previous breast surgery was more common in B vs. A (29.0% vs. 7.7%; P < 0.05), while bilateral surgery was performed more frequently in A vs. B (40% vs. 6.5%; P = 0.001). All SSM/SNSM for BRCA1/2 mutation were followed by immediate prepectoral implantation. No significant differences were found between groups in terms of post-operative complications. At pathology, DCIS and invasive ST forms, such as multicentric/multifocal forms, were detected more frequently in B, while NST type in A (all P < 0.05). A multivariate analysis showed improved post-operative satisfaction at BREAST-Q survey in Group A (P = 0.001). Encouraging oncologic outcomes after SSM/SNSM for BC enabled the improvement of breast reconstructive techniques. One-stage reconstruction is characterized by better aesthetic outcomes and by greater patient's satisfaction. When SSM/SNSM is technically difficult to perform, as in multicentric/multifocal forms or previous breast surgery, mastectomy followed by two-stage reconstruction should be considered to achieve a radical surgery.

We sought to analyse the effect of the introduction of intraoperative nerve monitoring (IONM) in our routine surgical practice and to provide a circumstantial analysis of direct costs of IONM in total thyroidectomy and of indirect costs associated with vocal fold palsy, as centred in the health care system of Italy. We retrospectively compared outcomes of 232 total thyroidectomies performed between November 2017 and October 2019, respectively, before (109 TT-Group A) and after (123 TT-Group B) adopting IONM technology in November 2018. We analysed the costs of IONM per procedure and rate and costs of vocal fold palsy events (temporary and permanent). Overall, there were 61 thyroid cancers (32 in Group B) and 171 multinodular goitres (91 in Group B). We recorded 5 cases of vocal fold palsy (4.6%—4 transient, 1 permanent) in Group A and none in Group B (p = 0.016). IONM consumables cost 219 eur per case. Healthcare and social cost of Vocal fold palsy ranged between 3200 eur (function recovery < 1 month postoperatively) and over 32,000 eur (permanent event). When only direct costs are considered, IONM can hardly be cost effective. In this study, cost of IONM implementation was offset by the absence of complications attributable to recurrent laryngeal nerve dysfunction. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic cholecystectomy is considered the gold standard for the treatment of gallbladder lithiasis; nevertheless, the incidence of bile duct injuries (BDI) is still high (0.3-0.8%) compared to open cholecystectomy (0.2%). In 1995, Strasberg introduced the "Critical View of Safety" (CVS) to reduce the risk of BDI. Despite its widespread use, the scientific evidence supporting this technique to prevent BDI is controversial.Methods: Between March 2017 and March 2019, the data of patients submitted to laparoscopic cholecystectomy in 30 Italian surgical departments were collected on a national database. A survey was submitted to all members of Italian Digestive Pathology Society to obtain data on the preoperative workup, the surgical and postoperative management of patients and to judge, at the end of the procedure, if the isolation of the elements was performed according to the CVS. In the case of a declared critical view, iconographic documentation was obtained, finally reviewed by an external auditor.Results: Data from 604 patients were analysed. The study population was divided into two groups according to the evidence (Group A; n = 11) or absence (Group B; N = 593) of BDI and perioperative bleeding. The non-use of CVS was found in 54.6% of procedures in the Group A, and 25.8% in the Group B, and evaluating the operator-related variables the execution of CVS was associated with a significantly lower incidence of BDI and intraoperative bleeding.Conclusions: The CVS confirmed to be the safest technique to recognize the elements of the Calot triangle and, if correctly performed, it significantly impacted on preventing intraoperative complications. Additional educational programs on the correct application of CVS in clinical practice would be desirable to avoid extreme conditions that may require additional procedures. [ABSTRACT FROM AUTHOR]

Recent evidence has proven the non-inferiority of laparoscopic complete mesocolic excision (LCME) to open complete mesocolic excision (OCME) with regard to feasibility and oncological safety. However, the differences in survival benefits between the 2 procedures have not been assessed. The aim of this study was to evaluate whether or not one procedure was superior to the other using updated meta-analysis. A systematic search for relevant literature was performed in Pubmed, Embase, Cochrane library and Google scholar databases. This meta-analysis included retrospective studies and one randomised controlled trial comparing LCME to OSCME. LCME to OCME was evaluated using updated meta-analysis. The Newcastle–Ottawa scale was used to assess the methodologic quality of the studies. Fixed- and random-effects models were used, and survival outcomes were assessed using the inverse variance hazard ratio (HR) method. Operative time was significantly shorter in the OCME cohort than in the LCME cohort. Blood loss, wound infections, time to flatus, time to oral feeding, and length of hospital stay were significantly shorter in the LCME cohort than in the OCME cohort. The 1-, 3-, and 5-year overall survivals were better in the LCME cohort than in the OCME cohort ([HR = 0.37 (0.22, 0.65); p = 0.004], [HR = 0.48 (0.31, 0.74); p = 0.008], and [HR = 0.64 (0.45, 0.93); p = 0.02], respectively). No difference in the 1-year disease-free survival (DFS) between the 2 procedures was observed ([HR = 0.68 (0.44, 1.03); p = 0.07]). In contrast, the LCME cohort had better 3- and 5-year DFS rates than those of the OCME cohort ([HR = 0.63 (0.42, 0.97), p = 0.03] and [HR = 0.68 (0.56, 0.83), p = 0.001], respectively). The results of the present study must be interpreted cautiously because the included studies were retrospective from single centres. Therefore, selection, institutional and national bias may have influenced the results. LCME is associated with the faster postoperative recovery and some better potential survival benefits than OCME.

Objectives: Pre-pectoral breast reconstruction is increasingly offered to breast cancer patients, as the one-stage technique has proved surgical and oncological safety and aesthetic effectiveness. Nevertheless, there are limited data on outcomes after pre-pectoral breast reconstruction in large and ptotic breasts. The aim of the paper is to present the authors' experience in performing Wise pattern mastectomy with pre-pectoral implant and complete acellular dermal matrix (ADM) coverage as a single-stage procedure in patients with large ptotic breasts. Materials and Methods: A retrospective review of protective collected data from January 2017 to June 2019 of patients who presented with large and ptotic breasts undergoing skin-reducing mastectomy and immediate pre-pectoral breast reconstruction with complete ADM coverage and inferior dermal sling was performed. Oncological and surgical outcomes were collected. Satisfaction with reconstruction and related quality of life were evaluated through BREAST-Q questionnaire. Results: Nineteen patients met the inclusion criteria. The average patient age was 55.6 years, and the mean body mass index was 31.2. Mean follow-up was 23.2 months from the initial reconstruction. One patient experienced seroma, and two cases of wound dehiscence at the T junction were observed and treated conservatively with no implant loss. All patients were satisfied with the final reconstruction. Conclusion: The Wise pattern skin-reducing mastectomy and pre-pectoral breast reconstruction could be offered to patients presenting with large and ptotic breasts. Future studies should better define long-term outcomes. Level of Evidence IV: This journal requires that authors assign a level of evidence to each article.

Biological meshes improve the outcome of incisional hernia repairs in infected fields but often lead to recurrence after bridging techniques. Sixty male Wistar rats undergoing the excision of an abdominal wall portion and bridging mesh repair were randomised in two groups: Group A (N = 30) using the uncoated equine pericardium mesh; Group B (N = 30) using the polyethylene oxide (PEO)-coated one. No deaths were observed during treatment. Shrinkage was significantly less common in A than in B (3% vs 53%, P < 0.001). Adhesions were the most common complication and resulted significantly higher after 90 days in B than in A (90% vs 30%, P < 0.01). Microscopic examination revealed significantly (P < 0.05) higher mesh integrity, fibrosis and calcification in B compared to A. The enzymatic degradation, as assessed with Raman spectroscopy and enzyme stability test, affected A more than B. The PEO-coated equine pericardium mesh showed higher resistance to biodegradation compared to the uncoated one. Understanding the changes of these prostheses in a surgical setting may help to optimize the PEO-coating in designing new biomaterials for the bridging repair of the abdominal wall.

The aim of this report was to illustrate a case of parathyroid carcinoma (PC) in a patient with multiple endocrine neoplasia type 1 (MEN1) along with a comprehensive literature review. A 61-year-old man presented with 9-cm PC causing primary hyperparathyroidism (PHPT). His pre-operative corrected calcium and intact PTH serum levels were 2.92 mmol/L and 391.7 pg/mL, respectively. The neoplastic gland was removed in bloc with thyroid and central compartment lymph nodes. A literature review was run by searching PubMed MEDLINE from 1977 to 2018 for studies of all types, in the English language only, using the terms “Parathyroid, carcinoma, Multiple endocrine neoplasia, type 1, (MEN1).” Pathology confirmed PC. Post-operative calcium and PTH levels were normal. A diagnosis of MEN1 was established post-operatively. Seventeen cases of PC in patients with MEN1 have been reported in the literature. 59% of patients were men, and median age at diagnosis was 50 years, with median serum PTH of 379 pg/mL and median serum calcium level of 3.2 mmol/L. The occurrence of PC in the context of MEN1 is extremely rare. Diagnosis and treatment may represent a challenge, so opportune identification or suspicion of malignancy and adoption of correct surgical approach may offer affected patients the best outcome.

The most appropriate surgical management of 'follicular neoplasm/suspicious for follicular neoplasm' lesions (FN), considering their low definitive malignancy rate and the limited predictive power of preoperative clinic-diagnostic factors, is still controversial. On behalf of the Italian Association of Endocrine Surgery Units (U.E.C. CLUB), we collected and analyzed the experience of 26 endocrine centers by computerized questionnaire. 1379 patients, surgically treated after a FN diagnosis from January 2012 and December 2103, were evaluated. Histological features, surgical complications, and medium-term outcomes were reported. Total thyroidectomy (TT) was performed in 1055/1379 patients (76.5 %), while hemithyroidectomy (HT) was carried out in 324/1379 cases (23.5 %). Malignancy rate was higher in TT than in HT groups (36.4 vs. 26.2 %), whereas the rates of transient and definitive hypoparathyroidism following TT were higher than after HT. Consensual thyroiditis (16.8 vs. 9.9 %) and patient age (50.9 vs. 47.9 %) also differed between groups. A cytological FN diagnosis was associated to a not negligible malignancy rate (469/1379 patients; 34 %), that was higher in TT than in HT groups. However, a lower morbidity rate was observed in HT, which should be considered the standard of care in solitary lesions in absence of specific risk factors. Malignancy could not be preoperatively assessed and clinical decision-making is still controversial. Further efforts should be spent to more accurately preoperatively classify FN thyroid nodules.

A 61-year old man with coeliac disease and chronic lack of appetite, malabsorption and weight loss, despite the gluten-free diet, was operated because of a sub-diaphragmatic free air due to a small-bowel pneumatosis cystoides intestinalis (PCI). The jejunum showed granulomatous lesions with a honeycombed appearance of air cysts in the submucosa/subserosa. We found overexpression of peptide YY (PYY) into only the jejunum with PCI, while the expression was very weak or absent in the tissue without cysts. One year after surgery, he had no abdominal pain or PCI recurrence. The above chronic symptoms were plausibly attributable to the PYY. [ABSTRACT FROM AUTHOR]

Purpose: To compare the outcome in patients with cervical goiters and cervicomediastinal goiters (CMGs) undergoing total thyroidectomy using the cervical or extracervical approach. Methods: This was a retrospective study conducted at six academic departments of general surgery and one endocrine-surgical unit in Italy. The study population consisted of 19,662 patients undergoing total thyroidectomy between 1999 and 2008, of whom 18,607 had cervical goiter (group A) and 1055 had CMG treated using a cervical approach (group B, n = 986) or manubriotomy (group C, n = 69). The main parameters of interest were symptoms, gender, age, operative time, duration of drain, length of hospital stay, malignancy and outcome. Results: A split-sternal approach was required in 6.5% of cases of CMG. Malignancy was significantly more frequent in group B (22.4%) and group C (36.2%) versus group A (10.4%; both P < .001), and in group C versus group B ( P = .009). Overall morbidity was significantly higher in groups B + C (35%), B (34.4%) and C (53.5%) versus group A (23.7%; P < .001). Statistically significant increases for group B + C versus group A were observed for transient hypocalcemia, permanent hypocalcemia, transient recurrent laryngeal nerve (RLN) palsies, permanent RLN palsies, phrenic nerve palsy, seroma/hematoma, and complications classified as other. With the exception of transient bilateral RLN palsy, all of these significant differences between group B + C versus group A were also observed for group B versus group A. Conclusions: Symptoms, malignancy, overall morbidity, hypoparathyroidism, RLN palsy and hematoma are increased in cases of substernal goiter. [ABSTRACT FROM AUTHOR]

The objective of this study was to compare the effectiveness of FloSeal® matrix hemostatic agent with hemostatic surgical procedures and Tabotamp® in thyroid surgery. One hundred fifty-five consecutive total thyroidectomy patients were recruited at our institution between January 2005 and December 2007. Exclusion criteria were applied. Patients were randomized to one of three hemostatic approaches: 49 received surgical procedures only, and 52 received oxidized regenerated cellulose patch (Tabotamp Fibrillar 2.5 × 5 cm) and 54 FloSeal (5,000 U/5 mL). The same surgeon performed all operations. Mean operating time was reduced in the FloSeal group (105 min) vs. surgical (133 min, p = 0.02) and vs. Tabotamp (122 min, p = 0.0003). Also, wound drain removal occurred earlier with FloSeal ( p = 0.006 vs. surgical; p = 0.008 vs. Tabotamp) resulting in shorter postoperative hospital stay in the FloSeal group ( p = 0.02 vs. surgical; p = 0.002 vs. Tabotamp). FloSeal matrix is an effective additional agent to conventional haemostatic procedures in thyroid surgery. [ABSTRACT FROM AUTHOR]
